(Note): Lamps are classified into the following ranks according to their luminous intensity.
Measurement tolerance for each limit is ±15%.
S: 1000−2000 mcd, T: 1800−3600 mcd, U: 3200−6400 mcd
Precaution
Please be careful of the followings

Soldering temperature: 260°C max Soldering time: 3s max
(Soldering portion of lead: Up to 2mm from the body of the device)
If the lead is formed, the lead should be formed up to 5mm from the body of the device without
forming stress to the resin. Soldering should be performed after lead forming.
This visible LED lamp also emits some IR light. If a photodetector is located near the LED lamp,
please ensure that it will not be affected by this IR light.
